IPC: H04R3/00
Filed: 2013-07-24
Abstract: A Sound Source Separation (SSS) method takes mixed audio signals signals (eg. from mics 1-M, 600) and performs a two-stage expectation-maximization (EM) on pairs of parameters (eg. spatial covariance matrices R and power spectra Ï

Title: Method and apparatus for controlling three-phase electric motor
Inventor: IGOR ALEXANDER TUREVSKY
IPC: H02P25/18
Filed: 2016-04-08
Abstract: A three-phase AC electric motor 1 is controlled by switching the motor windings between star and delta connections depending on torque requirements. The electromagnetic torque of the motor is monitored, and commands to switch from Star to Delta given when the electromagnetic torque rises to a first threshold and from Delta to Star when it falls to a second threshold. The motor may switch from Star to Delta or Delta to Star when the motor torque is substantially equal to the torque requirement of the load to maximise efficiency. Instantaneous values for the motor torque may be determined based on measurements of phase current and voltage at particular instants in the voltage cycle. Also disclosed are methods of timing the switching operation between Star and Delta, switching from Star or Delta to a dynamic braking mode, and minimising inrush currents by monitoring the vector relationship between EMF and supply voltage and performing switching operations in each motor phase when EMF vector is aligned with supply voltage vector. The motor may be an asynchronous motor, particularly to drive a mechanical load not requiring precise speed control, or having frequent start-up and braking cycles and variable loading.
